You can get all different kinds of fender mirrors from the typical black JDM fan boy DR3FTZZZ kind of ones , to the polished bullet shape ones I used on my ke70 so the choices are endless.
When ebaying mirrors don't "search ke70 fender mirrors" because you will be swamped in Fan boy gear , just search " fender mirrors " and they will be many to choose from.
depending on which type you get will depend where you mount them. use tape to dummy them up till you comfortable on where they sitting
they easy to mount, two holes into the fender and its done.
1 of the negatives is that your blind spot will increase , so you got to check over your shoulder more often.
